Hi I was wondering if someone can help me with an issue I don't understand. On the output drain of an RF FET transmitting at a VHF frequency under exceptional circumstances, i.e. an open circuit I have measured with an oscilloscope 6 X the FET supply voltage pk-pk, it does not die down and is a steady RF oscillation. I understand that poor mismatches can cause a standing reflected wave which can cause higher voltages but I don't understand how it is possible to achieve 6X the FET's supply voltage. Any ideas, thanks in advance
